I had drove my car to work on Tuesday the 19th. When I came back out to my car 6 hours later and started my car it was not moving at all there was a big clanking noise. I had parked my car and have not driven since I heard the noise. I had it towed to the shop. I feel as though this was something that happened out of the blue. I have kept up on my maintenance and everything and feel as though this must be a flaw with my car.

Went to go get an oil changed on Feb 9th. Monday, Feb 11th drove to work and back home, when I reached the exit off the beltway, the car started put puting, smoke started coming out of the back, engine and oil light came on. I immediately drove it 6 miles home to park it. Had it towed an hour later. The shop said the rod busted and went through my engine and no oil was in the car. This has been an ongoing issues with this type of car. This experience has really dramatized me. Not sure if my insurance will pay for it and I will have to come out of pocket to replace an engine that could have possibly been a recall. Based of my VIN: Its not, but January 2019 & April 2016, there were recalls with this same issue. Its not right.

On approximately April 30, 2018, while driving my Hyundai Sonata hybrid to montgomery Alabama I stopped to fill up on gas. After filling up I got back in my car and the car would not start my car, that's when I noticed the check hybrid system warning and check engine light came on. The steering was locked and the engine lost total power. Vehicle would not restart. Vehicle was stationary at a gas pump

On 4 separate occasions while traveling on highways at highway speed in ev mode, getting a warning "check hybrid system turn off engine" along with a check engine light; these are the occurrence dates 12/01/2017, 12/11/2017, 12/23/2017, 01/06/2018. Each time has been accompanied by a complete loss of gasoline engine availability resulting in a significant and unsafe drop in vehicle speed due to the car only being able to continue running on battery power. After pulling over I have been able shutdown the car and restart. Upon restart, the gasoline engine does come back on. Also note the "check engine" light has turned back off by the time I have taken the car back to the dealership. The car has been to the dealership twice now and supposedly repaired both times under warranty. The first repair attempt on 12/12/2017; the dealer was instructed by Hyundai to try tsb 16-01-020-1. the second repair attempt on 12/27/2017; there had been a P261F and P0A0F fault code and the dealer was instructed by Hyundai to replace all four spark plug coils. These attempts have not fixed the underlying problem as represented by the latest occurrence on 01/06/2018. This car is less than two years old and had only 36000 miles on it when this started happening.

Abrupt and total loss of acceleration at full throttle at or near high RPM shift points. This behavior can be reliably reproduced by "flooring it" (all the way, including kickdown) and not letting go - as if one is executing a passing maneuver. The power loss will occur at the next shift point after kick down, and will not be cleared until the accelerator pedal is released and re-applied - or after approximately 15 to 20 seconds after the occurrence if the driver does not release the pedal. In cases where the pedal is not released after the power loss, the vehicle will surge suddenly after the condition has cleared and repeat the behavior described above. This behavior can be reproduced in any drive program mode (eco, normal, sport, ) and in both automatic and manual shift selection modes, and is especially prevalent at speeds above 45 mph where sudden full throttle command causes kickdown. The drivetrain should respond reliably when it is commanded full-throttle. A sudden power loss at a shift point during a full throttle maneuver is unsafe: (1) it disorientates the driver and; (2) causes un-commanded, unexpected, and rapid changes in driving force, weight distribution, friction, and reaction forces which could lead to a loss of control.

I saw engine powertrain problem light on my car screen. So I went to capital hill hyndai dealer. I waited more than 6,5hour with eating breakfast and lunch at near mall. Hyundai explained just gas cap tighting problem. They never explained the process about six and half hour fixing. I need detail explanation about six hour fixing process and sincere apology about the engine problem sign in one week after buying new car.
